PRINTING-MACHINE.

SPECIFIGATIDN forming part of Letters Patent NO. 697,089, dated April 8,1902.

Application filed May '7, 1900. Serial No. 15,869. (No model.)

To all whom it may concern:

Be it known that I, ERNST JENSEN, a subject of the King of Saxony,residing at Munich, Bavaria, Germany, have invented certain new anduseful Improvements in Printing-Machines, of which the following is aspecification.

In the accompanying drawings illustrative of a machine constructed inaccordance with my invention, Figure I is a vertical longitudinalsectional View; Fig.II, an end elevation; Fig. III, a top plan view withpart of the handle broken away; Fig. IV, a plan view of the guide-railon a reduced scale, and Fig. V a transverse sectional view thereof.

Like letters of reference mark the same parts in all of the figures ofthe drawings.

The machine is provided with a hollow cylinder a, having interiorscrew-threads in its ends to receive screw-plugs (Z and e, which latterhave threaded openings in their outer ends to receive journals g and h.A pin w enters the edge of cylinder at and of a cylinder 1; to preventthem from moving upon each other. The design-roll c is carried by ahollow shell or double cylinder a2, mounted on cylinder Z), thedesign-roll being a cylinder of felt with or without the design brandedor burned in or on its periphery, or of soft gum, celluloid, hard gum,metal, or other suitable material, while the shell 00 is elastic andfilled with air and is to be removed or replaced with the designnoll. Inthe surface of cylinder c is a small semi-annular groove 3 to receivewards on the steel sheet of the guiderail M, Fig. IV.

The design -roll when of celluloid, hard gum, metal, or the like servesfor the production of cameo or intaglio designs on soft moist cement,plaster, asphalt, or the like.

The screw-plug c has formed with it a disk e, which serves as the headof said screwplug and holds the design-roll against endwise movement,while a similar disk-head d on the screw-plug d serves the same purposeat the opposite end of the design-roll. The disk (P has formed integralwith it a second disk cl, partially separated from it by an annularspace or groove of a width and depth conforming to the narrow part a ofthe guide rail, Fig. V.

The journals g and h are mounted in bearings in a bowf and may bereadily and easily placed in or removed therefrom bysimply unscrewingthem from the plugs 61 and e.

K indicates the reservoir for ink or color, which is secured to lateralprojections from the bow f by means of screws 8 and t, which enter slotsin said projections, whereby the distance of the reservoir from the axisof the design-roll may be regulated. (See Figs. I and IL) The reservoiris longitudinally slotted in its bottom to permit of the projectiontherethrough of an inking-roll m into contact with the design-roll, saidroll m being journaled at one end in the head Z of the reservoir and atits opposite end in a disk 0, seated in the opposite end of thereservoir and covered by the cap or head 1), said disk 0 being securedby a pin .2 and provided above the roll with an opening through which tofill the reservoir when the cap or head 19 is-re* moved. The steel sheeta secured upon the guide-rail it, forms the bottom of the groove to andhas formed upon its edge wards of, while the part a has openings ornotches u When the machine is to be started, it is placed upon the guiderail or disk d in groove to and part a in the annular groove betweendisks d and d and with pin 1; resting in any one of the notches oropenings 10' {of guide-rail u, so that the device will roll on theguide-rail away from or toward the handle thereof, as

desired, one of the wards 1L entering a groove y and the pin 0 enteringone of the notches n whereby the design-roll is kept from sliding andheld clear of the ink-roll during its movement in its eitherdirection.

Having thus fully described myinvention, what I claim as new, and desireto secure by Letters Patent of the United States, is

1. In a printing-machine, the combination with a hollow cylinder havinginteriorlythreaded ends, of screw-plugs threaded in said ends, a bow,and journals mounted in bearings therein and threaded into the outerends of the screw-plugs, substantially as described.

2. In a printing-machine, the combination with a hollow cylinder havinginteriorlythreaded ends, of screw-plugs threadedin said ends and havingthreaded openings to receive journals,said screw-plugs being alsoprovided with disk-heads and a design-roll held in place between saidheads, substantially as described.

3. In a printing-machine, the combination with a hollow cylinder, ofscrew-plugs threaded in the ends thereof, journals threaded in saidplugs, a bow having bearings for said journals, and projections radiallyslotted, and screws passing through the reservoir-shell and into theradial slots, substantially as described.

4. In a printingniaehine, the combination with the design-roll and itssupports, 00m-
